A paperwhite bulb is a bulb from the Narcissus papyraceus species, a type of daffodil that is easy to grow indoors for fragrant, pure-white flowers during the winter. These bulbs are known for their strong, classic scent (though some varieties are milder) and are often forced to bloom in pots filled with pebbles and water or well-draining soil. They are characterized by mid-green stems, strap-like leaves, and clusters of white flowers that typically last about two weeks.
